It will be understood that a key will be set in keyways E5 and G5.

The operation of my device is as follows: Let us assume that the mainsail has been fully wound around the boom B, and that it is desired to raise the mainsail. All that is necessary to do is to pull the mainsail up s5- by the usual sail halyardand as the sail goes up, the boom B can freely rotaterwith G1, G, Il, E', E1,E2 and E3. mainsa'i'lis'at its-ffull'height, and thefhandholderQE3 is in the4 positiorr jshown= in -VF ig. 1- hereof i thefhalyardv should be; f fastened oncleatE and also onv Vhand holder-E5, -So-that said. handfholderA E2 cannot-rotate;'which 1.

willfhold theboonr B -in nonrotatable lposi-V tionf.'v

Let us fnow* assumey that-v When the 'main- -l sail is thusiset at its Vfull'y height, it is 'then desi-red to reeflit.v All thatis neoessary,.-is, f,

toftake thehalyard offri-of cleat Fandhandfholder'Ef'and then rota-te E2' byYhand--ineither 1 direction, which 'will 'rotate' boom'fB, andwindl the mai-nsail onfboomB. Asfsoon" holder E3, which?asfjstatedwwill `preventfthe If it is then desired to entirely furlwthe mainsail, all that is necessary is to take the halyardv off of cleat F and hand holder E2, and then further rotate E5 by hand until the mainsail is entirely furled on boom B. VThen the hand holder E3 should be set in the position shown in Fig. l hereof, and the halyard should again be fastened on cleat F and also on hand holder E3, so that boom B cannot rotate. i

It will be further noted that in my device, the elements H and K permit the boom B to move sideways as far as desired at its after end; and the elements M and K2 permit the boom B to move upv or down as far as desired at its lafter end. It will be noted that the sideway movement of the boom at its outer end can be accomplished if H is fastened tight to G2 or to G3 or to both G2 and G2, and K is rotatable about H.' And also the sideway movement of the boom at its outer end can be accomplished if H is fastened tight to K, and H is rotatable through G2 and G5. And also the sideway movement of the boom at its outer end can be accomplished if H is rotatable through G2 or G2, or through G2 and G3, and K is also rotatable about H. And it will be further noted that the up or down movement of the boom at its outer end can be accomplished if M is fastened tight to either one or both of plates P, and K2 is rotatable about M. And also the up er down moveboom; B from rotatingg; e A

ment of the boom at its outer end can be accomplished if Mis fastened tight to K2, and M is rotatable through the two plates P. And also the up or down movement of the boom at its outer end can be accomplished if M is rotatable through one or both of the the claims herein, the words hand holderV will refeiI either to E2, or to E2 plus E3.

It will be further noted that the circular shaft H, being fastened at both ends in G2 andfGS, holds element K very firmly; and circularl shaft M, being fastened at both ends in plates P, holds element K2 very firmly. This makes it entirely safe for the upward pull of the mainsail on either' side of the boom B, when the mainsail is reefed in heavy weather, and hand holder E3 is fastened by the halyard to cleat E. It will of course be understood that my device can be used on a foresail, mizzensail, or any other form of sail.

The bolts S, shown in my Figs. 1 and 2, fasten my gooseneck C, D both above and ical equivalent of my various parts herein Y shown are a part ofv my invention, and of the claims herein.

I claim: Y

1. In a hand reefingboom; a. mast; a shaft located through said mast,said shaft beingA adapted to rotate 'said reeling boom; a gooseneck having a surface flat both vertical and sideway on the side of said kmast opposite the reefing boom; a fiat element fastened direct to said shaftsaid flat element being also rotatable directly against said fiat surface of thegooseneck; and a hand holder integral with and in alignment with said fiat element. I l z '2. In a hand reefing boom, a shaft located inside of said reeling boom, said hand reefing boom bein relation VtoV said sha t.
